Honey, I feel for you and hope you get the help you need here. I am sure you will..give the others time to chime in. At the amount you are taking it is possible rehab is the safer option. Have looked for other possible sites to check out?
It is possible you can start by tapering slowly? It will not stop the withdrawals, but it makes them more manageable. Please keep checking back. I am over 800 days free and it took 3 times for me to get it and get clean. I am 62 and at my age...I was afraid...but was able to finally get there. There are some non addictive meds that a doctor can prescribe that can help.
Look up the Thomas Recipe here:

for OTC help while you are detoxing. Starting them early before you begin the process is helpful as well.
I hope you find your way to sobriety. I am very glad you found this forum. It is active and thriving with help and support.
